that} To all whom it may concern: Be it known that l, Narnia McCor, a eitis zen of the United States, and a resident Marshalltown, in the county of Marshall and l State of iowa, have invented a new'and 1m proved Sight-Feed. Lubricator, of which the following. is a full, clear, and. exact descriptlon.

The object of the invention is to provide a.

device of that class in which the pump is utilized to force the lubricant through a transparent tube into the steam pipe or other part of the engine so that the manner in which the lubricant is being fed may be observed by the attendant. 1

The invention resides in certain novel features of construction and relative arrangement of parts which will be fully set forth hereinafter and particularized in the claims.

Reference is to be had to the accompanying drawings which illustrate as an example the preferred embodiment oflmy invention, in which drawings Figure 1 is a sectional view "of the inven-' tion; and Fig. 2 is a plan view with parts broken away.

The apparatus has a suitable frame 10 on which is revolubly carried a shaft 11. This shaft has a friction disk 12 attached thereto and coacting with said disk is an arm 14 which is arranged to swing on the shaft 11 alongside of the friction disk. The arm has a bracket 15 attached. thereto, and in this bracket-is held a roller 16 which coacts with a wedge 17 lying between the roller and the periphery of the friction disk 12.

18 indicates a spring yieldingly pressing the wedge 17 into active position. The arm 14 is connected by a link 19 orqother means with a moving part of the engine so that upon the operation of the engine the arm 14 is driven in unison with the engine. Upon swinging the arm 14 from left to right (referring to Fig. 1), the roller 16 will tend to ride down the wedge 17 and movement Wlll not be imparted to the disk 12 from said arm. Upon reversing this direction of movement,

however, heroiler terideup on the wedge 1'? arr-:1 thefwede'e intietween the roller and. frietien ear, an causing the disk and shaft to turn withthearm. The frame 10 has a tubniar extension 29 tb'which anarm 21 is keyed. This arm'is located at the side of the 12 opposite theerin 1.4, and has, a bracket 22 carrying a roller 23 w hich coacts with a wedge 24 and spring 25,

the same as the parts 16, 17 and 18 before described. Said wedge and spring, however,

are arrangedoppositely with respect to the wedge 17 and spring 18 and when the disk 12 is moving under the action of the arm 14 the disk tends to" push the wedge 24"from under the roller 23 and said Wedge does not inter fere with the movement of the disk. When, however, the arm 14 is returning from left to right to recover its engagement with the disk,

should the disk tend to turn from left to i right with the arm it will ride the wedge 24 tight in under'the roller 23 and this will stop the movement of the disk. It will be seen, therefore, that these parts 21, 23, 24 and 25 act as a dog for stopping idle movement of the disk. By these devices the shaft 11 is given a continuous step by step movement in unison with the operation of the cn 'ine or other machine in connection with which the lubricator is used. 9

Theframe 10 has a bracket-26 at one end, and a bracket 27 at the other end, which brackets are in alinementwit-h each other, shown. The bracket 26 carries a bushing 28 in which is loosely fitted a sleeve 29, the inner end of which. terminates in a flange 29*. Fastened to the sleeve 29 is a plunger rod 30, the outer end of which is threaded to engage a nut 31 which permits of the adjustment of the relative position of the sleeve 29 and rod 30. The opposite end of the plunger rod 30 passes thron -h a stuffingbox 32 formed on the inner end of the pump barrel 33 which is fastened link 35 with a sleeve 36 which. slides freely on p the plunger rod 30. 37 indicates a collar attached to the rod 30 adjacent to the stufling box 32. It will be;

seen that as the shaft 11 rotates the slide 36 plunger rod 30.

moves on the plunger rod and upon striking on one hand the collar 37 and on the other the flange 29 of the sleeve 29 a back and forth movement will be imparted to the plunger rod The degree of this movement may be readily regulated by adjusting the position of the nut 31 and sleeve 29.

The pump barrel 33 communicates with achamber 38, the walls forming which are preferably integral with the pump barrel, and the communication between the pump barrel and chamber being intermediate the ends of the chamber. I At the receiving end the chamber is provided with an automatic valve 39 to which a tube 40 leads from the lubri cant reservoir 41. The upper part of this reservoir is in communication with the boiler or other source of fluid pressure by a pipe 42 passing into the top of the reservoir. In this manner the lubricant is positively fed intoeffecting a tight joint. 1 In practice the tube 46 and branch 47 is filled with water, a nd the lubricant is permitted to flow in drops upward through the water so that the feeding of the lubricant may be observed. The waterkeeps the oil in separate drops and enables the feed to be clearly seen.

In the operation of the device, the link 19 being in connection with the moving part of the engine, the vibration of the arm 14 will cause the shaft 11 to rotate and the plunger rod 30 to be driven or struck, all of which depends upon the adjustment of the elements 29 and 31.

forces a part of the lubricant out through the valve 43. This it will beobserved provides for extremely delicate adjustment of the oil supply, the pump being used solely as a means for passing out the desired quantlty of lubricant as coutta-distinguished from per forming as well the function of drawing the lubricant into the pump.

l-l'avii'ig thus described the preferred form of my invention, what I claim as new and desire to secure by Letters Patent is:
